Ultrasonicassisted machining of silicon carbide (SiC) ceramic matrix composites (CMCs) has the ability to decrease grinding force and improve processing quality. The machining process often produces large cutting forces which cause defects, such as delamination and burrs, due to the brittleness and high hardness of the material. Therefore, it is significant to precisely predict the grinding ...
